Definition
Interpersonal neurobiology studies how relationships and attention patterns shape neural integration and felt safety over time.
IPNB frames mind as an embodied, relational process regulating energy and information flow — integration of differentiated neural systems is the core health marker.
Mechanism
Attention between people shapes neural coupling over time — co-regulation is not metaphor. When felt safety drops, integration work (naming, pacing, repair) becomes the training surface before louder strategy or visibility moves. Siegel’s frame treats integration of differentiated systems as the health marker — not fusion, not isolation.
Applications
Useful when visibility, couple field, or client holding must be read as co-regulation, not solo willpower.
